Web Forms :: How To Keep Controls Appear In Absolute Positions In Design Mode
Mar 19, 2010
I have some controls within panel control.
In the deisgn time they all appear 0th position on panel.
if the textbox's top is defined as 250px, in the design time also it should appear exactly at 250Px position instead it is appering at the 0px of panel.
all controls are appearing at the top of panel frame.
this problem i didn't see in vs 2003 1.1 framework, usign vs 2008 it started.
But at runtime they do appear perfect what ever the position they were suppose to.
I know for sure i may have to do some settings on the VS ide.
Using VS 2010 Beta 2, VB, to make hidden panels visible during design time, I have the panels away from the main form and then use Javascript to position them during runtime. This works fine except that when I use a footer on the masterpage, the footer shows up at the bottom of the page as if the page is the complete length of the desing page, and not the page that is being viewed. For example, I might have a panel that is absolute positioned to be 2000px from the top. During design view, the panel is easy to see and edit, but the content page would then be a height of 2000px. Using a javacript function, I position the panel to be at 100 px from the top upon pageload. During runtime, the page is viewed normal, but if you look at the page, there is a scroll bar to the right since the page shows to be 200x height until the javascrip function postitions it correct for viewing. Using a master page, the footer then shows up after the content page, which is 2000px down. Any ideas of how to make this work without changing what I do for editing? I am sure there is a better trick to editing layers, but I haven' found it. For example in Autocad, you just make a layer (panel) visible or invisible while editing. I haven't figured out how to do that with VS.
I'm playing around with dependency injection in a web-forms website al a Ninject and whilst I have had no problem at all getting the site running smoothly I've had a pretty big problem when viewing individual pages using design mode.
I wouldn't normally use design mode but dragging and dropping web user controls onto a design space is the easiest way by far to add them to a page.
The set-up is pretty much identical to guidelines here The error on the design page is thus:
The type "page name" requests an injection, but no kernel has been registered for the web application. ensure that your project defines a NinjectHttpApplication.
I'm using Asp.Net 4.0 with Ninject and Ninject.Web 2.2 utilizing property injection
The method GetDesignTimeHtml of the ControlDesigner class should return html markup that will be shown on the page in design time. My problem is that control looks different in different versions of the visual studio. What is the rendering engine visual studio use to render control in design mode?
I have a simple HttpHandler that generates a dynamic image based on query string parameters and a custom web control that renders an image tag pointing to the handler as its 'src' attribute. All works fine when run in the web server, but at design timethe control displays as the "missing image" icon (red x in a box). The handler is registered in the web.config with a ".ashx" extension. The RenderContents method in the control looks like this:
When I use SQL Server 2005 it's possible to change table in design mode. But when I use SQL Server 2008 I can not Add, Delete, Arrange or Change the Data Type. When I save it then Error Display
"Saving Changes is not permitted. The changes you have made requaire the following table to be dropped and re-created."
I'm not sure if I'm placing this in the right spot but since it has to do with Entity Framework I put it here. Here's the deal. I have a FormView bound to an EntityDataSource. The FormView is a part of a user control. In design view on the user control, the formview and the entity datasource show up as expected. However once I put the user control in an aspx page, the formview won't show up. The entity datasource shows, but the formview doesn't.
Instead I get this message in design view: "There was an error rendering the control. Value cannot be null. Parameter name: owner" I don't have any parameters in my datasource or formview called owner. Is it talking about the database owner. By way of comparison, I put a SqlDatasource on the page and tied it to a formview. It showed in design view on both the user control and the aspx page. So that led me to believe it has something to do with the formview being bound to the entity datasource.
Visual Studio ( VSTS 2008 ) design mode work good for long time and from about 2 weeks ago it's suddenly stop view any thing in design mode i tried a lot with trying in another projects even in a simple web page but no way it's doesn't view any thing in design mode ... I think to reinstall VS 2008 again but I don't know if is there any outher solution for that ?
As far I know this is not supported for asp.net projects. It's quite handy for testing static/shared functions.any info if this will be available in future versions? Or if there are any alternative ways to test your functions in design mode?
This error only happens when I launch an existing application, if I create a new app the error does not appear on that site. However if I try to enter Design mode the Windows Installer opens and hangs. I can still edit the code and even launch the app.
If I click "OK", I get a dialog box that starts a Windows Installer that does not install anything, it justs sits there. If I "cancel" the installer, VWDE dies.
The only thing different on my laptop is that I had Office 2007 Trial installed along side Office 2003 before I installed VWD, I then uninstalled the trial and used the clean-up tool at [URL] to clean up the trial.
I have tried to repair VWDE, I have uninstalled and reinstalled VWDE with no change. Ialso have VB Express running and get no errors when launching it.
I use ResolveClientUrl to include css files in my page. When launched through web-server everything is OK, but in design mode css styles are not applied to the page. I use VS 2010 beta 2.
I installed Visual Studio 2008 in my machine. Both c# and vb.net are working properly, but my problem is asp.net is not working. If we are taking a new website project there is no design mode in default.aspx means at the bottom there is no design, source, split. If we go to View->Design then one error message is popup that there is no editor available for this Default.aspx. Again in Tools->Options->Html Designer will shows that an error occurred loading this property page. My OS is Windows Xp Professional 2002, IIS is also checked on .I don't know what to do.....
What is the correct code to append text to the END of the content inside the HTMLEditor in design mode with a button click?In this case,there will be no cursor position set,hence the value will be 0, and the text is inserted at the beginning of the html within the HTMLEditor.This is what I am using to insert the text where the cursor is:
Is there a way to know what parameters are needed by an event in Visual Studio 2010?Let's say I have a DropDownList control and I want to bind a method to the "OnSelectedIndexChanged", I would do something like thisn the ASPX File:

MVCThe generated ADO.NET Entity Data Model loses ordinal positions of columns and reorders Entity Set column names alphabetically. This causes the columns in a new MVC VIEW to appear alphabetically and needs to be reordered by hand. I am using MySQL Database.
How can I retain the ordinal positions of columns?
Without using a Table (html or asp version), I'd like to align the Labels with the ListBoxes under them. There are 3 Labels and under them 3 Listboxes. I tried this:
[Code]....
When I look in the Immediate Window in VS, they all say "Nothing" (ex: ListBox6.Style.Item("left"))
Is there a good way to do this or am I going to have to deal with Tables?
suppose i've created my own user control, and it has a textbox and a property for the textbox so that if i use the user control from within the aspx file, i can give the property a value. for example:
[Code]....
is it possible to also set the property to be seen via the desing mode , just as it works for other (built in) controls? maybe a different method to implement the same scenario?
if you still didn't understand what i mean : after setting the value of DefaultNum1 via the code i've written here, i expect the textbox associated with this property to be updated as well to '1' via the design mode (and split mode). of course it won't work using the current method, since VS cannot guess what is going on with the property and understand that all of its purpose is to assign an initialization value for the textbox.
After I imported a VS 2008 web project to VS 2010, I can't view aspx pages that have master pages in design mode. The page design mode displays "error creating control - contentplacehoder1 object reference not set to an instance of an object." The project builds and runs fine though. I have only one master page that all other aspx pages reference and I don't have any nested master pages.
gaining mode changing for formview in VB.The problem is that, the current mode im using was ReadOnly, and i want to add some button so thatit could connect to Edit mode in the same formview.Is it necessary to add modechanging and modechanged in the back code?
I have looked at all the posts I can find on this problem and tried everything I can think of, but still the problem persists. I am getting really sick of it.was working fine for the last year until an update to MS Office 2007 caused a lot of problems (automatic update). After checking posts here, I removed it completely. No change. I then tried all the things I could find on other posts, also no change. Today, I removed VS and the Web Authoring Component and re-installed. Still no go.
Does anyone have a fix for this problem. It seems that it has been around a long time, but is still giving problems. I even saw one suggestion to reformat the drive! You've got to be joking!
